Simply put: YES this is hazing. It is a situation that is created intentionally or unintenionally that creates discomfort and/or embarassment. It should not be done. The problem here is that since these girls are officers they are putting your entire chapter (and charter) at risk with their behavior. I wouldn't go straight to your HQ because they usually take pretty strong action that you might not be ready for. It doesn't sound like the problem is widespread or out of control. Best if you handle this matter internally if possible and then ask for help if necessary.
